  • Patent number: 4272838
    Abstract: An electronic watch module structure adapted to be disposed and supported by a case body of the watch. The module structure comprises a plastic base which has a first axial recess formed on one side of the plastic base, a second axial recess formed on the other side of the plastic base, a circuit board disposed in the first axial recess, an electro-optical display cell disposed on one side of the circuit board, and retaining means for retaining the display cell in a fixed place relative to the circuit board.
    Type: Grant

  • Patent number: 4202166
    Abstract: A solid state watch module construction has a ceramic substrate on which an integrated circuit chip is mounted to provide drive signals for causing an electro-optical display means to indicate the time. The ceramic substrate is interposed between a battery supporting frame and a cell supporting frame which positions the electro-optical display means with respect to the substrate. The battery supporting frame holds a battery in place, which is retained by a battery retaining member. A connector member is disposed between the ceramic substrate and the electro-optical display means to provide electrical connection therebetween. A plurality of tubes are used for fixedly connecting the battery supporting frame and the cell supporting frame.

  • Patent number: 3975896
    Abstract: A switching mechanism for an electronic timepiece is disclosed. The switching mechanism comprises an external means for selectively activating an internal switching assembly. The external means is rotatably coupled to a grooved rod member which is in turn coupled to the internal assembly. Various contact arms disposed across the grooved rod member are adapted to become selectively disposed on various electrical contacts in the timepiece. By rotating the grooved rod member, these arms are selectively disposed on or off corresponding electrical contacts thus causing the internal switch assembly to be turned ON or OFF. By the use of the invented switching mechanism, various internal switching assemblies such as for alarm systems and the like may be easily activated and deactivated without the problems associated with prior art switching mechanisms.
